Page  273  Limits on _asm Identifiers

Never use reserved assembly words as labels, variable names, or other
identifiers within an _asm block. This includes words in the following
categories:

   ASM Opcodes such as CMP or MOV
   Opcodes new to the 80186, 80286, and 80386 such as ARPLS or CLTS
   Reserved operand words such as WORD or PARA
   C library functions such as "exit" or "time".

For example, the following code is not permitted:

   main()
   {
     int word;
     _asm{mov WORD PTR [word], ax }
   }

The variable "word" can be used in the C part of the program, but not
within the assembly block.
